After upgrade cannot access order details or product details in Upgrading PrestaShop from a previous version Posted September 13 39 minutes ago, musicmaster said: Interesting. According to PS documentation it should work with PHP 7.2. What error message did you find? I asked my hosting provider for help with logs, because I am not familiar with server settings/errors and they are very nice, prompt and helpful, so why not? That was their answer and I think it might have sense. This may cause an issue to anybody with PS 184.108.40.206 and PHP 7.2 and other language(s) installed. I am sorry, I currently do not have a test website and cannot reproduce the error (and solution) again, to confirm it for sure. I can only say that switching to PHP 7.3 definitely helped me now.
